San Anselmo sits deep in the Ross Valley under oaks and redwoods, along a creek with a history of flooding downtown. Many homes are older, shaded and built over crawlspaces. That combination makes mold a common problem here, especially after a wet winter. We find the moisture, contain the area, remove the growth to IICRC S520 standards and confirm the result.

Allied Restoration serves Downtown San Anselmo, Sleepy Hollow, the Seminary area, Red Hill, Oak Knoll, Yolanda and the Butterfield and Sir Francis Drake corridors from our Petaluma office at 15 Copeland Street, Petaluma, CA 94952, with a 60-minute emergency response target and IICRC-certified technicians on every job.

Why San Anselmo Homes Get Mold

The causes we see most in San Anselmo:

Creek flooding downtown — San Anselmo Creek has flooded downtown in major storms. Flooded buildings that were not fully dried often show mold in walls months later.
Shaded canyon lots — Homes under heavy tree cover in Sleepy Hollow and the hills dry slowly after rain, and north walls can stay damp all winter.
Older crawlspaces — Homes from the early 1900s through the 1950s often have dirt crawlspaces without vapor barriers, wetting subfloors from below.
Roof and gutter overflow — Leaf-filled gutters overflow into walls and foundations in the first big storms of the season.
Bathrooms without exhaust fans — Older bathrooms vented only by a window build up moisture daily.

Had water in the house recently? Mold remediation works only after the structure is dry. If the water is recent, start with flood damage repair in San Anselmo.

Frequently Asked Questions

My crawlspace smells musty. Is that mold?

Often, yes. A musty smell from a crawlspace usually means mold on joists or subfloor, or wet soil. We inspect the crawlspace, take moisture readings and tell you what is actually there before recommending work.

Is mold remediation covered by insurance?

It depends on the cause. Mold resulting from a sudden covered water loss is often covered, sometimes with a limit. Mold from long-term leaks or humidity usually is not. We document the cause so your adjuster can decide.

Do you replace what you remove?

Yes. After clearance, our reconstruction team replaces drywall, insulation, trim and flooring so you deal with one company.

Yes. Allied documents every job in Xactimate — the estimating format every major carrier uses — and coordinates directly with your adjuster from first call to final repairs.
